I really see no reason to change at all. I may get an itch and use Motorcraft 5W30 once to see what the oil pressure gauge does.

The gage won't do anything. It doesn't actually read pressure. It just shows it either has it or not. It's a dummy gage. Doesn't give variable data, just go or no go for having oil pressure.
